this is what western madagascar is like.... nutshell... It is why my G grandidieri like water but also can deal with dry and it is the way I will strive to keep The Opisthicanthus.
" The western coast of Madagascar is much drier than the eastern coast. In general, we can say the climate here is dry tropical. During the dry months between May and November it does not rain at all and the temperatures are pleasant (20 to 25°C on average). Between December and April it can rain torrentially or just a couple of showers, depending on the are and the year. The northern area is greener and indeed considerably wetter than the southern one. The hottest months are March, April, November and December, when the average temperature is 30° C or even more. "
